766 simulationStepsPerTimeUnit is the number of simulation steps per unit of time used by VISSIM 766 simulationStepsPerTimeUnit is the number of simulation steps per unit of time used by VISSIM (second)
767 for example, there seems to be 5 simulation steps per simulated second in VISSIM, 767 for example, there seems to be 10 simulation steps per simulated second in VISSIM,
768 so simulationStepsPerTimeUnit should be 5, 768 so simulationStepsPerTimeUnit should be 10,
769 so that all times correspond to the number of the simulation step (and can be stored as integers) 769 so that all times correspond to the number of the simulation step (and can be stored as integers)
